Another 51 companies have joined the Open Invention Network, an association through which members share intellectual property related to open source Linux.

The group, which is based in Durham, now has more than 460 partners.

OIN supports a shared patent portfolio for the further development of Linux.

“The next generation of Linux adoption is coming from the convergence of big data and analytics, cloud computing, smart mobile devices and mobile broadband, and social networking,” said Keith Bergelt, OIN’s chief executive officer. “OIN’s licensees during 2012 reflect this trend, as indicated by the participation of companies such as Mellanox, Qisda, and others.”
